• For an 8-quart Instant Pot, you must increase the broth to 1 1/2 cups.
• The sauce is fatty (but flavorful). If it’s too much for you, skim its surface with a flatware spoon before serving— or just let it sop into crusty bread or even mashed potatoes.
• For an even richer sauce, remove the beef and all vegetables, leaving the sauce in the pot. Bring that sauce to a simmer with the SAUTÉ function on HIGH, MORE, or CUSTOM 400°F. Cook, stirring occasionally, until reduced to half its original volume, 6–8 minutes. Then stir in up to 1 cup buttermilk until smooth and bring the sauce
back to a boil. Boil for 2 minutes, then turn off the SAUTÉ function and remove the (hot!) insert from the pot.
